Abstract

The surface tension of mixtures including low GWP refrigerants, 50 mass % HFO-1234yf/50 mass % HFC-32 and 50 mass % HFO-1234ze(E)/50 mass % HFC-32, was measured by the differential capillary-rise method in the temperature range from 273 K to 323 K. On a basis of the present data, correlations were formulated as a function of temperature by the expression of van der Waals type. A mixing rule for the coefficients in correlations of pure components was discussed for representing the data of mixtures. It is found to be difficult for representing the data of mixtures by a simple mixing rule.
